Methods to tag objects in a cloud computing environment, by tagging an object with a first tag, of a plurality of tags, wherein each of the plurality of tags specifies a respective criterion for objects tagged by each tag, and upon determining that the object not satisfy the criterion of the first tag, performing an action associated with the first tag to modify the object to meet the criterion of the first tag.

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of co-pending U.S. patent application Ser. No. 14/451,569, filed Aug. 5, 2014. The aforementioned related patent application is herein incorporated by reference in its entirety.

BACKGROUND

The present invention relates to computer software, and more specifically, to computer software to perform actions on objects as a result of applying tags to the objects.

Tags have traditionally been used to organize files and other computing resources. Tags are typeless, in that a user may assign any type of meaning to any tag, without computer software understanding what the tag signifies. However, simply tagging an object does not cause the object to comply with the meaning of the tag.

SUMMARY

Embodiments disclosed herein include systems, methods, and computer program products to tag objects in a cloud computing environment, by tagging an object with a first tag, of a plurality of tags, wherein each of the plurality of tags specifies a respective criterion for objects tagged by each tag, and upon determining that the object not satisfy the criterion of the first tag, performing an action associated with the first tag to modify the object to meet the criterion of the first tag.

DETAILED DESCRIPTION

Embodiments disclosed herein associate textual tags with specific actions, such that when the tag is applied to computing objects, the actions are run in order to configure the object (or dependent objects) to comply with the tag. Tags may be applied directly to objects in a cloud computing environment, such as a computing resource or a workload to be deployed in the cloud computing environment. The computing resource may be hardware, software, or any combination thereof. The workload may be tagged with specific resource requirements, such that the resources targeted by the tagging are configured to be in compliance with the tag's criteria.

A tag, as used herein, refers to a textual metadata classifier that annotates (or classifies) an object with a set of criteria. Furthermore, a tag, as used herein, may provide an associated set of actions that cause tagged objects to comply with the criteria, if the tagged objects do not already comply with the criteria. If the tagged objects already comply with the criteria, the objects may be classified without acting on them. The tags may coexist with conventional tags in the same namespace. As used herein, an object may refer to, without limitation, any computing resource (software, hardware, or both), workflow, or workload.

For example, a user may define a “grayscale” tag that causes digital photographs and other digital images to be processed so that they have a grayscale color depth, if they don't have the grayscale color depth already. The user may associate the grayscale tag with a script that is configured to apply grayscale color depth to the digital images. When a user subsequently tags a digital photograph with the grayscale tag, the script may be invoked to convert the digital photograph from color to grayscale. As another example, a user may define an “EnergySaver” tag that may initiate actions and policies to adjust power capping, energy usage, and migrate virtual machines in order to shut down servers to save energy. When the user tags a virtual machine image with the EnergySaver tag, subsequent deployments of the virtual machine image will be deployed to a cloud computing configuration that complies with the predefined power saving techniques and requirements.

In any case, tagging objects as disclosed herein may be used to not only classify objects, but to configure objects so that they are altered to reflect the tag's meaning, and to specify requirements for workloads that have not yet deployed. Embodiments disclosed herein allow users, who tag existing resources with a specific purpose (as defined by the tag), to configure new resources for the same specific purpose without having to run complex actions and configurations each time. Furthermore, since tagging is used for classification and filtering, embodiments disclosed herein allow users to use the tag to understand which resources comply with the tag, as well as which resources are being configured to comply with the tag. The tag may specify any requirement, including, without limitation, as minimum resource allocations, operating parameters or environment, security parameters, virtual resource configurations, quality of service, class of service, and the like.

FIG. 1 depicts a graphical user interface (GUI) 100 to perform actions on objects as a result of applying tags to the objects, according to one embodiment. As shown, the GUI 100 lists different resources in a cloud computing environment. In this example, the resources are the objects to which tags are applied. Each resource includes a name 101, a type 102, a category 103, and a set of tags 104. The name 101 may be a name of a resource, such as the servers 1-3, and the workflow 1. The type 102 indicates a type of the resource, such as an x86 computer, Power7 server, or disk image. The category 103 indicates a category the resource belongs to, such as compute node or image. Although depicted to facilitate explanation of the disclosure, the type 102 and the category 103 are not required to enable tagging of an object. A tag may be applied to any label or identifier sufficient to uniquely identify an object. The tags 104 are a set of user-defined tags that have been applied to the object, in this example, servers and a workflow. The tags may be associated with a specified set of criteria and a set of actions that alter the resource to make the object comply with the set of criteria. Generally, a user may define any number and type of tags for any object. When a user wishes to apply a tag to an object, the user may apply any feasible method to apply the tag. As shown, for example and without limitation, a user is typing a tag 105, which is the DualVIOS tag. A popup notification 106 indicates that the user may apply the tag by pressing enter. The user may define the DualVIOS tag to be associated with two redundant virtual I/O servers. In defining the DualVIOS tag, a user may specify one or more criteria and associated actions. In one embodiment, the user may tag existing scripts used to deploy the dual virtual I/O servers, configuration patterns, or other templates that contain configuration information for the dual virtual I/O servers. Additionally, workflow images may be tagged, thereby specifying specific criteria that need to be present in order for the workload to be deployed in a data center.

Generally, when a user tags an object, embodiments disclosed herein may reference a data store of existing tags to determine if the tag has previously been defined. If the tag has not been defined, the user may specify the criteria and associated actions that cause different objects to comply with the tag. As such, users can apply previously defined tags, as well as create tags in a freestyle and ad hoc manner. If the tag has already been defined, the criteria and actions may be retrieved in order to ensure that the object complies with the tag.

When the user enters the tag 105, embodiments disclosed herein may analyze server 3 to determine whether the server is compliant with the tag. To determine if server 3 is compliant with the DualVIOS tag, the tag requirements may be compared against the current configuration of server 3. For example, a data store reflecting the status, capabilities, and configuration of server 3 may be referenced to identify whether it currently is executing (or is capable of executing) the dual virtual I/O servers. Additionally or alternatively, the resource (server 3) may be queried directly (or through a proxy, such as a management controller) to determine if server 3 is executing the dual virtual I/O servers. If server 3 is not currently executing dual redundant virtual I/O servers, embodiments disclosed herein may initiate a predefined set of actions to deploy the dual virtual I/O servers onto server 3. A user may optionally be prompted to approve the changes to server 3 prior to deploying the dual virtual I/O servers.

As another example, as shown, workflow 1 has also been tagged with the DualVIOS tag 104, as the workflow requires the two virtual I/O servers to run properly. When workflow 1 is subsequently deployed in a cloud computing environment, embodiments disclosed herein may enforce the DualVIOS tag 104 by ensuring the deployments include the dual virtual I/O servers. If, for example, active host servers having the dual virtual I/O servers configured, embodiments disclosed herein may deploy the workflow 1 to one or more of such active host servers. If active host servers are not found running dual virtual I/O servers (or that are capable of hosting dual virtual I/O servers), embodiments disclosed herein may scan other resources to find host servers in stand-by or other low priority pools that are compatible. This compatibility may be determined, as discussed above with reference to server 3, by referencing stored information of the stand-by servers, or retrieving the capabilities and current configuration of the stand-by servers directly (or by proxy). Once a compatible server is identified as a target, embodiments disclosed herein may tag the resource with the DualVIOS tag, which initiates the re-configuration of the server to include the dual virtual I/O servers. Once the configuration of the servers is complete, the workload may be deployed to the target server.

Generally, users may define any type of tag specifying any number and type of criteria, as well as any associated actions. As another example, a user may tag a compute node with a “PowerVC1” tag, which causes the node to be registered with a management application named “PowerVC1.” Appending the tag DualVIOS to the compute node tagged PowerVC1 would cause the node to be added to the hardware management console (HMC3), installing two virtual I/O servers on the tagged node, and then adding the node into the PowerVC1 management application.

FIG. 2 depicts a system to perform actions on objects as a result of applying tags to the objects, according to one embodiment. The networked system 200 includes a computer 202. In at least one embodiment, the networked system 200 is a cloud computing environment. The computer 202 may also be connected to other computers via a network 230. In general, the network 230 may be a telecommunications network and/or a wide area network (WAN). In a particular embodiment, the network 230 is the Internet.

The computer 202 generally includes a processor 204 connected via a bus 220 to a memory 206, a network interface device 218, a storage 208, an input device 222, and an output device 224. The computer 202 is generally under the control of an operating system (not shown). Examples of operating systems include the UNIX operating system, versions of the Microsoft Windows operating system, and distributions of the Linux operating system. (UNIX is a registered trademark of The Open Group in the United States and other countries. Microsoft and Windows are trademarks of Microsoft Corporation in the United States, other countries, or both. Linux is a registered trademark of Linus Torvalds in the United States, other countries, or both.) More generally, any operating system supporting the functions disclosed herein may be used. The processor 204 is included to be representative of a single CPU, multiple CPUs, a single CPU having multiple processing cores, and the like. The network interface device 218 may be any type of network communications device allowing the computer 202 to communicate with other computers via the network 230.

The storage 208 may be a persistent storage device. Although the storage 208 is shown as a single unit, the storage 208 may be a combination of fixed and/or removable storage devices, such as fixed disc drives, solid state drives, SAN storage, NAS storage, removable memory cards or optical storage. The memory 206 and the storage 208 may be part of one virtual address space spanning multiple primary and secondary storage devices.

The input device 222 may be any device for providing input to the computer 202. For example, a keyboard and/or a mouse may be used. The output device 224 may be any device for providing output to a user of the computer 202. For example, the output device 224 may be any conventional display screen or set of speakers. Although shown separately from the input device 222, the output device 224 and input device 222 may be combined. For example, a display screen with an integrated touch-screen may be used.

As shown, the memory 206 contains a tag application 212, which is an application generally configured to apply user-defined tags to computing objects, and cause user-defined actions to be applied to tagged objects. Generally, users may define any types of tags, which may be stored in the tag data 215. If the user creates a tag that has not been previously defined, the user may specify the tag criteria and any associated actions that may be performed in order to cause tagged objects to comply with the tag criteria. When a user applies a tag to an object, such as hardware, software, or a combination thereof, the tag application 212 may identify the tag criteria, and compare the criteria to the tagged object. The object properties may be stored in the object properties 217, or the object properties may be retrieved by querying a resource, or an application managing the resource. If the object complies with the criteria, the tag application 212, in some cases, may not take any further action. If the object does not comply with the tag criteria, the tag application 212 may perform one or more predefined actions to bring the object into compliance with the tag. The actions associated with the tag may be stored in the action items 216. For example, if a user tags a server as “webserver,” the tag application 212 may identify the corresponding tag in the tag data 215, identify any action items 216 (user defined or otherwise) that cause a server to be configured as a web server, and execute the steps necessary to configure the server to host a web server. Additionally, the tag application 212 may group objects with common criteria together.

As shown, storage 208 contains the tag data 215, action items 216, and object properties 217. The tag data 215 contains a plurality of tags that may be applied directly to an object, such as a computing resource or a workload that targets computing resources. The tags in the tag data 215 may be associated with specific criteria and a set of actions that may alter a resource to comply with the tag criteria. The action items 216 is a repository of computer-executable code, scripts, or other configuration methods that may alter objects in order to make the resources comply with different tag criteria. In at least one embodiment, the action items 216 may themselves be tagged with tags from the tag data 215. Similarly, the tag data 215 may specify associated items in the action items 215. Doing so associates the tags in the tag data 215 with predefined actions in the action items 216, which allows the tag application 212 to ensure that objects are configured according to the tag criteria. The object properties 217 is a store configured to hold configuration information and other attributes of objects in the system 200. The object properties 217 may generally include configuration and attributes of computing resources or workflows. For example, hardware configurations, software configurations, and other information about one or more hosts 250, virtual machines, and other computing resources may be defined. In addition, the object properties 217 may also specify each tag that has been applied to each object.

The hosts 250 are compute nodes which perform different computing functions. For example, the hosts 250 may be configured to execute one or more virtual machines 261, or store data in storage locations 262. In one embodiment, the hosts 250 may be compute nodes in a cloud computing environment.

FIG. 3 depicts a method 300 to perform actions on objects as a result of applying tags to the objects, according to one embodiment. Generally, the steps of the method 300 run a set of predefined actions when a user applies a textual tag directly to a resource, or in reaction to a workflow or workload being deployed that is tagged with specific resource requirements, such that the resources targeted by the tagging are configured to be in compliance with the tag criteria. In at least one embodiment, the tag application 212 performs the steps of the method 300.

At step 310, a user may define tag attributes, criteria, and associated actions that are performed responsive to a user tagging an object with the tag. For example, a user may define a “SecurityCertified” tag, which may specify a set of security parameters for a hardware object, software object, or combination thereof. The tag attributes and criteria may be stored in the tag data 215. The user may further specify actions associated with the tag, such as applying security to communications transmitted by the object, configuring firewalls, and the like. The associated actions may be stored in the action items 316. At step 320, the tag application 212 may receive user input tagging an object with a tag. Generally, the user may tag any object in a computing environment with a tag, such as a computer, networking device, software image, files in storage locations, and the like. For example, the user may tag a compute node (i.e., a server) in a cloud computing environment with the SecurityCertified tag. The tag application 212 may also store the tag in a record for the tagged object in the object properties 217, reflecting that the tag has been applied to the object. At step 330, the tag application 212 compares the tag criteria, which may be stored in the tag data 215, to the object's current configuration. The tag application 212 compares the object properties to the criteria in order to determine whether the object complies with the tag criteria. For example, the tag application 212 may determine whether the server, tagged with the SecurityCertified tag, complies with the predefined attributes and criteria of the SecurityCertified tag. The tag application 212 may retrieve the server properties and configuration information from the object properties 217, the server itself, or a proxy, such as a management controller that manages the server.

At step 340, the tag application 212, upon determining that the tag criteria are not met, performs the actions associated with the tag in order to cause the object to comply with the tag. The associated actions may be, without limitation, a script, set of actions, or other configuration methods that may alter objects to make the object comply with the tag criteria. For example, the tag application 212 may cause firewalls to be configured, enable encryption on the server, and the like. Generally, the tag application 212 may cause any action to be taken to configure the tagged object, or resources that the tagged object targets.

As an example involving tagging a workload, the user may apply the SecurityCertified tag to a workload image. When the workload is subsequently deployed, the tag application 212 may ensure that the resources the workload is deployed to comply with the SecurityCertified tag. For example, the tag application 212 may identify resources that comply with the SecurityCertified tag attributes. If the tag application 212 does not find any matching (tagged) resources, the tag application 212 may automatically tag the existing resources to cause existing resources to be reconfigured to comply with the tags. Once SecurityCertified resources are configured, the SecurityCertified workload may be deployed to the resources for processing.

FIG. 4 depicts a method 400 corresponding to step 340 to perform actions associated with a tag, according to one embodiment. Generally, the steps of the method 400 result in the reconfiguration of resources such that the resources comply with the tags applied to different objects. The tagged objects may be resources, data, or any combination of hardware or software. Additionally, the tagged objects may be workflows targeting different computing resources in a cloud computing environment.

At step 410, the tag application 212 may optionally prompt for user approval prior to triggering the actions to change the computing resources affected by the tags applied by the user. At step 420, the tag application 212 may generally invoke any associated scripts, patterns, or other templates that include configuration information designed to bring tagged objects into compliance with the tag criteria. For example, if a user tags a file as PasswordProtected, the tag application 212 may invoke a script which applies a password to the file. The script may apply a default password, or prompt a user to specify the password. If the object is a resource, the tag application 212, by the invoked actions at step 420, causes the resource to be configured to comply with the tag criteria at step 430. If the tagged object is a workload, at step 440, the tag application 212 may identify existing targets (such as compute nodes) satisfying tag requirements. If the tag application 212 finds no such existing resources, the tag application 212 may identify existing resources capable of meeting tag criteria. The tag application 212 may then tag these resources such that they are reconfigured to meet the tag criteria. At step 450, if the tagged object is an item in storage, the tag application 212 causes the item in storage to be modified to meet tag criteria. For example, if a user tags a digital photograph with a specified image format, the tag application 212 may invoke the necessary actions to convert the photograph to the specified image format. Generally, the tag application 212 may invoke any number of actions in order to cause the object to meet any number of criteria specified in the tag.

FIG. 5 depicts a graphical user interface 500 to use tags in an infrastructure lifescycle, according to one embodiment. Generally, applying tags to objects in a computing environment allows the tags to be leveraged in order to manage the computing environment. In some computing environments, hundreds of thousands, if not millions of objects, need to be managed. As shown, the GUI 500 provides a set of tags 510 that a user can select in order to filter the resources down to only those resources having the specified tag. Therefore, when the user selects the Website tag 512, only those resources tagged with the Website tag may be displayed. In addition, a set of tools and actions scoped to the selected tag may be displayed. For example, and without limitation, elements 511 and 512 allow a user to deploy a Website workload and add website resources, respectively. When the user selects the elements 511 or 512, any added resources or workloads would be tagged with “Website,” and any hardware configuration to make the newly added hardware compliant with the Website tag would be performed automatically. In addition, different management tools 520, 530, 540, 550, and 560 allow users to view management providers, workload statuses, workloads with issues, hardware maps, and capacity/policies related to the selected tag, respectively. Generally, the tools 520-560 are small views that summarize different categories of objects so that in one dashboard, many kinds of objects can be seen in summary. For example, if a user clicks “Website,” the user instantly sees any object tagged with Website. In addition, in tool 520, the user would see how many hardware management consoles and how many virtual management consoles are involved in managing the web sites. In tool 530, the user would visualize how many workloads in the datacenter are contributing to the web sites. In tool 540, the user would see how many workloads contributing to web sites have problems. Using tool 550, the user would see what actual hardware components (computers, storage, network) are supporting the web sites. Finally, using tool 560, the user would receive an aggregate ‘utilization’ view highlighting how many resources and what kinds of policies are manipulating the web sites.

Advantageously, embodiments disclosed herein provide textual tags that are associated with predefined criteria and actions, such that when the tags are applied to objects in a computing environment, the actions are executed in order to configure the object (or dependent objects), such that the object complies with the tag. The tags may be applied to physical or virtual resources, software, data, and any other component in a computing environment. By defining a tag, users can configure items without substantial effort. Tagging, which is a universal way to classify objects, may therefore be extended to configure objects such that they are altered to reflect the tag's meaning. Furthermore, the tags may specify requirements for workloads that have not yet been deployed. When the workload is subsequently deployed, the workload may be deployed to underlying resources that comply with the tag criteria.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

For convenience, the Detailed Description includes the following definitions which have been derived from the “Draft NIST Working Definition of Cloud Computing” by Peter Mell and Tim Grance, dated Oct. 7, 2009, which is cited in an IDS filed herewith, and a copy of which is attached thereto.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 6, a schematic of an example of a cloud computing node is shown. Cloud computing node 610 is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node 610 is capable of being implemented and/or performing any of the functionality set forth hereinabove.

In cloud computing node 610 there is a computer system/server 612, which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server 612 include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like.

Computer system/server 612 may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server 612 may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

As shown in FIG. 6, computer system/server 612 in cloud computing node 610 is shown in the form of a general-purpose computing device. The components of computer system/server 612 may include, but are not limited to, one or more processors or processing units 616, a system memory 628, and a bus 618 that couples various system components including system memory 628 to processor 616.

Bus 618 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.

Computer system/server 612 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server 612, and it includes both volatile and non-volatile media, removable and non-removable media.

System memory 628 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 630 and/or cache memory 632. Computer system/server 612 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 634 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 618 by one or more data media interfaces. As will be further depicted and described below, memory 628 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.

Program/utility 640, having a set (at least one) of program modules 642, may be stored in memory 628 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules 642 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.

Computer system/server 612 may also communicate with one or more external devices 614 such as a keyboard, a pointing device, a display 624, etc.; one or more devices that enable a user to interact with computer system/server 612; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server 612 to communicate with one or more other computing devices. Such communication can occur via I/O interfaces 622.
